HYDROCARBON-BURNER.

Specification of Letters Patent.

Patented Dec. 19, 1905.

To (LZZ whom it may concern:

Be it known that LWILLIAM EMoCoNNELL, a citizen of the United States, residing at Kansas City, in the county of Wyandotte and State of Kansas, have invented certain new and useful Improvements in Hydrocarbon-Burners, of which the following is a specification.

My invention relates to hydrocarbon-burners; and my object is to produce a device of this character for use especially in burning crude oil which operates efliciently and reliably.

A further object is to produce a burner of this character of simple, strong, durable, and cheap construction.

With the above-named objects in view the invention consists in certain novel and peculiar features of construction andorganization, as hereinafter described and claimed, and in order that it may be fully understood reference is to be had to the accompanying drawings, in which Figure 1 represents a view, partly in side elevation and partly in vertical section, of a burner embodying my invention. Fig. 2 represents a section taken on the line II II of Fig. 1.

In the said drawings the burner shown is in the form of a cylindrical cap, consisting of the top portion 1, having a central opening 2, the depending box or chamber 3, preferably circular and concentric of and surrounding opening 2 and provided with a series of radial orifices 4 and the depending annular marginal flange 5, concentrically surrounding and projecting beyond the lower end of box or chamber 8, said flange 5 having a series of jet-orifices 6 in radial alinement with orifices 4 and of flaring form at their inner ends, as at 7.

Projecting vertically upward from the cap and having its passage forming a continuation of opening 2 is a short tube 8, and mounted rigidly upon and communicating with said tube is a mixing-tank 9, the same being preferably of circular form, with its center in vertical alinement with the center of the burner. Tapped into a boss 10 of said tank and communicating with the latter is a short pipe 11, controlled by a needle-valve 12 of the wellknown or any other suitable type and containing between said needle-valve and the tank an asbestos wick 13 for the purpose of supplying water to the tank by capillary attraction in case the flow of water through said pipe should be temporarily interrupted, this water being supplied, through the medium of the piping 14, from a water-tank, (not shown,) said water-tank being preferably disposed in a higher plane than the mixing-tank of the burner. Tapped into a boss 15 of said tank and communicating with the latter is an oilpipe 16, controlled by a needle-valve 17 of any suitable type, and conducting oil to said pipe 3 16 from an oil-tank (not shown) is a pipe 18, said oil-tank, like the water-tank, being disposed in a higher plane than the mixing-tank. By this arrangement of said tanks oil and water are supplied by gravity, though it is obvious that they may be otherwise forced into the mixing-tank. As this burner is designed primarily for use in heating and cooking stoves and furnaces, where means for forcing the oil other than by gravity would be objectionable on the ground of expense and inconvenience, the use of the supply-tanks for water and oil to supply such liquids by gravity is preferred.

In practice after the burner and superposed mixing-tank have been heated in any suitable manner to-a sufficient temperature to thoroughly vaporize oil in limited quantity the operator manipulates the needle-valves sufficiently to permit the required quantity of oil and water to pass into the mixing-tank, where the oil is instantly converted into vapor and the water into steam, this vapor and steam becoming intimately mixed and superheated and then passing down through tube 8 into the box or chamber. From chamber 3 the superheated mixture of vapor and steam is discharged outwardly through orifices A and jetorifices 6 of flange 5,the suctional action of such discharge taking with it a volume of air from the-annular mixing-chamber formed by the space between the box or chamber and the flange, the volume of air thus mixed with the mixture of vapor and steam being controlled to some extent by reason of the fact that the flange depends below the box or chamber. This mixture of oil, steam, and air produces a highly-inflammable gas, which is ignited and burns fiercely at the outer ends of the jet-orifices 6 and supplies the heat not only necessary for heating or cooking purposes, but also to keep the superposed mixing-tank at the required temperature for instantly converting any oil and water entering the same intovapor and steam, respectively, it being understood that the heat generated is usually sufficient to vaporize all of the oil and water before they reach the mixing-tank and that in consequence the chief function of the mixingtank is to efiect the intimate admixture of the vapor and steam which enters it.

I have found in practice that with a hydrocarbon-burner of this type the crudcst kind of oil can be burned with the best resultsthat is to say, not only will it generate heat in a most reliable manner, but it accomplishes such purpose economically.

From the above description it will be apparent that I have produced a hydrocarbonburnerpossessing the features of advantage enumerated as desirable and which obviously vburner having a box or chamber provided with orifices, and a flange surrounding said box or chamber and provided with jet-orifices in radial alinement with the box or chamber orifices, and disposed some distance outward from said box or chamber to provide a mixing chamber or space between them, in combination with a mixing-tank for vapor and steam, disposed above the burner and communicating with the box or chamber thereof.

2. A hydrocarbon burner, comprising a burner having a box or chamber provided with orifices, and a flange surrounding said box or chamber and provided with jet-orifices in radial alinement with the box or chamber orifices, and disposed somedistance outward from said box or chamber to provide a mixing chamber or space between them, in combination with a tube communicating with the box or chamber, a mixing-tank communicating with the tube vertically above the burner, and means for supplying oil and water to said mixing-tank.

3. A hydrocarbon burner, comprising a burner having a box or chamber provided with orifices, and a flange surrounding said box or chamber and depending below the same and provided with jet-orifices in radial alinement with the box or chamber orifices; said flange being disposed outward of the box or chamber to provide between them a mixingchamber for air and the vapor and steam discharged from said box or chamber and means for supplying mixed steam and oil-vapor to said box.

A. A hydrocarbon-burner consisting of a mixing-chamber, means for supplying oil and water to said chamber, an outlet-tube depending centrally from the mixing-chamber, and a cylindrical cap secured centrally on the lower end of the outlet-tube and having an annular depending flange provided with radial jet-orifices and a central box or chamber surrounding the end of the outlet-tube arranged concentric with the depending flange and provided with jet-orifices in alinement with the orifices in the flange, the annular space between the box and the flange constituting an air-and-vapor-mixing chamber.

In testimony whereof I aifix my signature in the presence of two witnesses.
